Lesion associated with the 89E breakpoint lies between 183 and 184 kb.
Male and female genitalia and analia are missing or abnormal in homozygotes. Parasegment 14 is partially transformed into parasegment 13, and there is a rudimentary setal belt in A9 in homozygous embryos.
Hemizygous individuals have abnormal posterior spiracles and a rudimentary ninth ventral setal band.
Revertant of dominant Tab phenotype. When hemizygous, shows stronger transformation of the eighth ventral setal band toward that of the seventh than does Abd-Biab9-Tab/Df(3R)P9; also, abnormal posterior spiracles and a rudimentary ninth ventral setal band.
Complements iab-5 and iab-6 alleles.
Revertant.
